My nose hump is getting bigger. Any suggestions?

There are many possible causes for a bump on the nose including the ones you mention.  You should schedule an appointment with a rhinoplasty surgeon for a complete evaluation and to discuss the cause and possible treatment options

Rhinoplasty is the only way to reduce your hump. Pressing it will not do anything except make it red and larger if scar forms. 

The dorsal hump is composed of both bone and cartilage must be shaved down surgically to remove it. Pressing on it manually will do nothing. Once the hump has been shaved down, osteotomies of the nasal bones are required to narrow the bridge line. Closed rhinoplasty techniques can accomplish the goals of hump removal. .  Digital computer imaging would also be helpful to understand what can be accomplished with your nose upon your facial features. For many examples, see the link below

All of these could be possible regarding your nasal bump. It is difficult to say what is wrong with your nose without reviewing photos. Your next step should be to schedule a consultation with a rhinoplasty surgeon to get a thorough evaluation including photos and computer imaging to better understand the procedure and to clarify expectations. Best of luck to you.

you should consider stopping pressing on your nose as it may be making is larger. This may be occurring as you may be irritating the underlying tissues resulting in more scar tissue. Scar tissue may feel quite firm. This is just a consideration. Your nose may also be naturally growing. It seems that you are concerned about a hump which can be eliminated with a closed rhinoplasty.  A consultation would be helpful.
